I noticed his form has dropped off lately could this have something to do with it??
Casboult is a big lump of a player and a contested marking machine with bucket hands; he can hoof the ball, but still after several years he has a very poor technique as far as his ball drop and kicking for goal is concerned (looked to have improved a bit early on this year by modifying his run-up but still needs to address the fundamental biomechanical/mental issues). More importantly, I believe he lacks a bit of self-belief, and even mongrel, which is something that helps players fight to stay in the game for four quarters and build consistency over a season. One of the best strong marks in the league, but alas, a couple of things let him down (consistency and accurate kicking for goal) - not worth c. $500K per year at this stage (if only he could kick for goal like Fev!).
